This example use fiber-swagger and swaggo (Go converter to Swagger Documentation 2.0)

1. Download swaggo by using:

   $ go get -u github.com/swaggo/swag/cmd/swag
   
   # 1.16 or newer
   $ go install github.com/swaggo/swag/cmd/swag@latest

2. Add comments to your API source code (example: handlers/book.go) or more details: swaggo documentation.

3. Download fiber-swagger by using:

   $ go get -u github.com/arsmn/fiber-swagger/v2

4. Import to your routes file (example: routes/routes.go):

   import swagger "github.com/arsmn/fiber-swagger/v2"

5. Add swagger handler to routes as a middleware (example: routes/routes.go):

   app.Get("/docs/*", swagger.Handler) // default
   
   app.Get("/docs/*", swagger.New(swagger.Config{ // custom
   	URL: "http://example.com/doc.json",
       DeepLinking: false,
   }))

6. Run the swaggo command in your Go project root directory which contain main.go file. This command will generate required files (docs and docs/doc.go)

   $ swag init

7. Import docs directory that generated by Swag CLI to your main.go file:

   import _ "swagger/docs"

8. Horray! You're ready to Go 🚀
